My kids could probably spend all day just with the dinosaur exhibit. We also got to see butterflies this time! There's plenty to see, and so much of it is hands on for kids to get to experience. Being right on the Ben Franklin parkway, there's a ton of stuff within walking distance. Parking isn't too difficult but it's in Center City Philly so it isn't super cheap either.
